Unexpected opening deserves attention because it can affect security and may point to a control, remote, wiring, or opener problem.
Safe observations
- Remove obvious remote-control interference
- Check whether a remote button is stuck
- Notice whether the opener behaves unexpectedly at other times
- Avoid making unsafe electrical modifications
